LLM carbon calculator
Rough-but-sourced CO₂ for inference: tokens × model coefficient. For ISVs and sustainability teams who need the same numbers in production, the REST API and dashboard add history, tenants, and PDFs.
Search engines surface many tools when people look for an LLM carbon footprint calculator or LLM CO₂ calculator. This page is carbon-llm's answer: transparent coefficients, an interactive estimate, and an upgrade path to API-based tracking — not a black box.
Competitors such as standalone calculators (e.g. public “LLM emissions” sites) optimize for quick guesses; we optimize for traceability (see methodology) and repeatable measurement via /v1/estimate and /v1/track.
